Slimline IBM DVD drive up for sale

I currently have this DVD drive available for sale:

Slimline laptop DVD drive with tray load system, pulled out from IBM laptop - so it also includes IBM faceplate. It is in working condition, tested with both DVD and CDROM media. Its beeing said its IBM drive, but according to model number mentioned on drive label I believe its in fact Matsu****a OEM drive. What is unique on this drive is it has Master/Slave/CS IDE switch (most newer drives are directly hardcoded to Master state!).
